Looking Ahead
Light to moderate winds are forecast through the weekend with an increase in windward showers through the weekend as an old front pushes south over the islands. Wet windward weather is expected to continue next week as trade winds bring enhanced moisture into mauka spots too.
Today
We expect northeast winds around 5 to 20 mph. High temperatures are forecast from 82° to 87°. Mostly sunny skies for leeward spots with clouds building in the afternoon and isolated showers. Partly cloudy with scattered showers for windward areas in the late morning and afternoon.
